I have to say I'm quite curious about this too as I arrive at x =1.

WARNING ! : under no circumstance should my result be seen as correct as I have been using forbidden dark math, astrology and some alchemy to get there, which has litterally cost me an arm and a leg and my cat's soul is now attached to the coffee maker.

I also hate the fact I have write an apology to the teacher to whom I said : I'll never have to use this ever again !

That made my day ^_^ As to the math problem, sorry but I have no clue >_< The only math that's drilled into my head currently is Stats @_@ Best of luck though!

Ok how about this one

You square both side and get:

2x - 1 = 16 + (x - 4) - 8(x - 4)^(1/2)
8(x - 4)^(1/2) = 13 - x
64(x - 4) = (13 - x)^2

then do the rest.....

BTW, I cannot add.....

So please verify the equation.... I might add wrong

EDIT: x = 85, or 5.

I think your head aches from doing crazy math problems like THAT, not from ice skating, Harry!! Kittens, you are da WOMAN!! My English-major noggin simply BOGGLES at the sight of all those numbers with the weird symbols all around 'em.

eeeeek! All you math-types are amazing.

Awwwwwwwwwwwww.... Thanks

But if you give me real numbers instead of simbols, I start making mistakes

I prefer dealing with all simbols over real fixed numbers

Really, I cannot add real numbers

(all of my students know it too

)

That isn't the first time I've made that mistake. See what happens when you rely on computers to do everything?

Hmmmm.. darn I knew how to do these problems eyes closed a few years ago.. sigh it's so impressive how much the brain forgets over time

. Let me try to work these out for ya ^_^.

Edit: oooo Kittens is good LOL

2nd Edit: for the 2nd problem, wouldn't you just need to do ^4 on each and simplify?

STATS!! HE SAID STATS!! aaaaaaahhhhh

If I see anything that even remotely resembles a mathematical symbol my brain turns to curds and whey. Even though I know I can actually do the thing. It's called "math anxiety."

*sigh*

Kittens, when I saw the title of this thread I was expecting you to be the first reply... LOL!
